Math Problem Statement

If pp is false and qq is false, find the truth value of: p, and, \neg, q p∧¬q

Solution

Given that pp is false and qq is false, let's evaluate the expression p¬qp \land \neg q.

Step 1: Identify the truth values

  • p=falsep = \text{false}
  • q=falseq = \text{false}

Step 2: Determine the truth value of ¬q\neg q

  • ¬q\neg q is the negation of qq.
  • Since q=falseq = \text{false}, ¬q=true\neg q = \text{true}.

Step 3: Evaluate p¬qp \land \neg q

  • p¬qp \land \neg q is the logical "and" of pp and ¬q\neg q.
  • The "and" (\land) operation is true only if both operands are true.

In this case:

  • p=falsep = \text{false}
  • ¬q=true\neg q = \text{true}

Since one of the operands is false, p¬qp \land \neg q is false.

Final Answer:

The truth value of p¬qp \land \neg q is false.

  2. How does the truth value change if pp is true and qq is false?
  3. What is the truth value of ¬(pq)\neg (p \land q) given p=falsep = \text{false} and q=falseq = \text{false}?
  4. How do logical operators like \land and ¬\neg relate to circuits in computer science?
  5. What happens if both pp and qq are true in the expression p¬qp \land \neg q?

Tip: When working with logical expressions, constructing a truth table can be a helpful way to visualize all possible outcomes.
